GAS-HEATER.

Specification of Letters Patent.

Patented July 20, 1909.

Application filed February 4, 1909. Serial No. 476,128.

To all whom it may concern: 1

Be it known that I, JAMES A. EDDY, a citi- Zen of the United States,residing at McAle's'ter, in the county of Pittsburg and State ofOklahoma, have invented certain new and useful Improvements inGas-Heaters, of which the following is a specification.

This invention relates "to heating apparatus and more particularly togas heaters,

and has for its object to provide a heater so arranged that it willstore heat to be radiated for a considerable time after the gas has beenturned off.

Another object is to provide a structure including sand, as a heatconserving agent and embodying a structure facilitating the changing ofthe sand when desired.

Other objects and advantages will be apparent from the followingdescription and it will be understood that changes in the specificstructure shown and described may be made within the scope of the claimswithout departing from the spirit of the invention.

In the drawings forming a portion of this specification and in whichlike numerals of reference indicate similar parts, in the several views,Figure 1 is a side elevation of the present heater, Fig. 2 is a verticalsection through the heater, F i 3 is a horizontal section on line 33 ofFlg. 2. Fig. 4 is a top plan.

Referring now to the drawings, the present invention comprises a bodyportion 5 including a cylindrical outercasing 6, having supporting legs7 at its lower end. Attached to the legs 7, there is an annular bottomplate 8, secured at its outer periphery to the edge of the casing 6 andhaving secured to its inner edge a frusto-conieal hollow member 9, openat its upper portion as shown at 10. The bottom of the member 9 is alsoopen, and located within the lower portion of this member, there is a asburner 11, supplied through the medium 0 apipe 12.

Located within the casing 6. and disposed in spaced relation thereto,there is an inner cylindrical casing 14, having an annular bottom plate15, to the inner periphery of which there is attached the lower edgeportion of an upwardly extending conical member 16 which thus lieswithin the casing 14. This inner casing 14 is so disposed that theconical member 9 extends within the member 16, the inner casing 14 isstationary, the annular bottom 15 resting upon suitably shaped brackets17 which are secured to the outer casing 6 at its lower edge, and whichextend upwardly and inwardly therefrom. The cylinder 14 has a top roundedge 18, providedwith an opening 19, and within the cylinder 14 there isdisposed a quantity of sand 20, which has a level spaced from the topedge 18.

In the top plate 21 of the cylinder 6, there is a central openin 22located above the opening 10, and this opening is surrounded by anupwardly extending circular flange 23 considerably spaced from theopening 22, and having a plurality of perforations 23 as shown. Theflange 23 carries a plate 24 which deflects the heat outwardly throughthe perforations 23'.

The bracket 17 has openings therethrough as will be understood, and theconical 'memher 9 being spaced from the member 16, the

air passes up into the member 16 and being heated by the burner 11,tends to accumulate within the member 16, thus heating the sand. Theheated gases pass downwardly between the members 9 and 16, however, anda current of air thus passes upwardly between the brackets 17 andthrough the space between the inner and outer casings, passing outthrough the opening 22 and thence through the perforations 23. p Thesand 20 accumulates heat, as stated, and this heat has access to thespace between the top 18 of the cylinder 14 and the top of the casing 6.

The top'of the casing 6 is raised back on the hinge 27 as shown, and theinner casing 14 may thus be emptied of the sand therefrom through theopening 19, when desired.

A handle 25 is carried by the plate 24 and by it the stove may betransported from place to place, it being understood that a fastener 26is provided to hold the top plate 21 to the outer casing 6 in closedposition.

What is claimed is 1. In a heater, the combination with an outer casing,of an inwardly extending bottom plate carried by the casing, said bottomplate having an opening therethrough, an upwardly extending open toppedhollow frusto-conical member secured to the bottom plate and disposedabove the opening of the bottom plate, supports secured within thecasing, an inner casing disposed upon the supports, an upwardlyextending hollow conical member located within the inner casing, saidfrusto-conical member extending into the conical member in spacedrelation thereto, heat conserving material located within the innercasing and surrounding the conical member, said inner casing beingdisposed in spaced relation to the outer casing, a removable top for theouter casing, said removable top having an opening therethrough, and aheat deflecting plate located above the opening.

2. A heater comprising an outer casing having an inwardly extendingbottom plate, supporting legs carried by the bottom plate, an upwardlyextending open topped frustoconical hollow member secured at its loweredge portion to the inner periphery of the annular bottom plate, aburner located within the hollow member, inwardly extending bracketscarried by the casing and surrounding the hollow member, an inner casinghaving an annular bottom plate disposed upon the brackets and having anupwardly extending hollow conical member secured to the inner edge ofthe annular plate, said frusto-conical member extending into the conicalmember and lying in spaced relation thereto, a quantity of sand locatedwithin the second casing and surrounding the conical member, said innercasing having an opening at its top, a removable top for the outercasing, said removable top having an opening therein, means for holdingthe removable top in position at times, an upstanding flangevsurrounding the opening in the removable top, said flange beingprovided with perforations, and a plate secured upon the'upper edge ofthe flange.

In testimony whereof I aflix my signature, in presence of two witnesses.
